摘　　要：基于玉米生产成本的上涨,建立超越对数成本函数模型,利用1999—2018年20年的面板数据探究玉米生产要素之间的替代关系。结果表明,种子对土地的替代关系呈现先上升后平稳的态势;机械要素对土地的替代呈现出略有下滑、基本平稳的趋势;化肥对土地的替代关系呈现波浪形趋势,但始终维持在较高的替代水平。机械对劳动力的替代关系基本呈现平稳态势,但从其他各类要素对劳动力替代效应的程度来看,机械对劳动力的替代效果更加显著。Based on the rise of maize production cost,this paper established the transcendental logarithm cost function model,and explored the substitution relationship among maize production factors by using the panel data from 1999 to 2018.The results showed that the substitution relationship of seed to land increased first and then stabilized;the substitution of machinery showed a slight decline and basically stable trend;the substitution relationship of chemical fertilizer to land showed a wave trend,but always maintained at a high level.The substitution relationship between machinery and labor force is basically stable,but from the perspective of the degree of substitution effect of other factors on labor force,the substitution effect of machinery for labor force is more significant.
